Normally reload all my rounds, have done some TSS #7 and lead #5. Last year I got a deal on some Hevi-13 3" 2oz #7, decided to give them a try. Through my Beretta 390 and Trulock .660 ported was getting 240 hits in 10" at 40 yds, pretty impressive stuff. All birds have dropped instantly, only thing I didn't like about them was finding pellets in meat, something you don't have to worry about with the TSS #7
